It's a 5 stage interview process, and each round is important. The first round checks your basic coding language knowledge. The second round is a coding round, focusing solely on technology, not algorithms or data structures. The third round is with the manager to assess your decision-making and past experience. The fourth round is with the engineering director, and the fifth is with HR. The last two rounds are mainly to see how well you collaborate and communicate.
